Cellulosic Ethanol Falls A Few Billion Gallons Short

Ten years ago a visionary named Vinod Khosla gave a presentation called Biofuels: Think Outside the Barrel. It seems to have disappeared from his Khosla Ventures website, but you can find an archived version here. In that presentation Mr. Khosla outlined his vision for biofuels. He projected that ethanol produced from biomass – aka “cellulosic ethanol” – would scale up rapidly. From zero commercial production in 2006, Khosla foresaw the first 100 million gallons of cellulosic ethanol hitting the market in 2008 (see Slide 78), ramping rapidly to 2.5 billion gallons in 2011, 14.6 billion gallons in 2015, and ultimately 173 billion gallons per year by 2030. Combined with corn ethanol production, he believed cellulosic ethanol could totally end U.S. dependence on petroleum for transportation fuel – but he needed to get the government on board to foot some costs.

Khosla addressed potential obstacles in his presentation. Certainly cellulosic ethanol wouldn’t fail because of technology. There were too many companies working on it. The magic of Moore’s Law and black swans would be the ticket to success. (As an aside, he doesn’t seem to understand the black swan theory, as he frequently cites these “high-profile, hard-to-predict, and rare events” as an expected outcome). The only real barrier he could identify was those despicable oil companies, who had to be shaking in their boots that this 100-year old upstart technology would spell their demise.

But he would deal with the oil companies through legislation by forcing them to purchase this product that had yet to be commercialized. So he lobbied, and he testified before Congress. He lost a vote or two, but he was instrumental in getting cellulosic ethanol mandates included in the Renewable Fuel Standard (RFS) in the Energy Independence and Security Act of 2007. The EPA was charged with implementing the RFS, and they based the mandated volumes on the amount that potential cellulosic ethanol producers claimed they would be able to produce. For 2010 the EPA was counting on 100 million gallons of cellulosic fuels based on claims primarily from two companies associated with Vinod Khosla: Range Fuels and Cello Energy. CONTINUE»

Everything Old is New Again; Biofuels, Still a Bad Idea

I recently recieved two emails on the same day; one about more palm oil plantations usurping yet another tropical ecosystem, this time for highly endangered African Gorillas instead of Indonesian Orangutans, and the other from my local Sierra Club asking me to urge my elected representatives to reject a transportation funding bill that would not allow our Governor to mandate the consumption of biofuels. Instead, I wrote a letter to the editor of the Seattle Times expressing my opposition to a biofuel mandate (which, of course, wasn’t published). I put a copy of that rejected submission at the end of this post as an example of what not to send to the Seattle Times Op Ed department.
